Migrating a GraphQL API Backend from FaunaDB to DynamoDB

Are you looking to migrate your database backend to a more scalable cloud infrastructure without disrupting your existing frontend application? Transitioning your data layer can be daunting, but with the right architectural approach, you can swap your underlying database smoothly and maintain API contract stability. This written course guides you through replacing FaunaDB with DynamoDB as the data store for a GraphQL API with zero client-side modifications. You will learn how to map your existing data models, rewrite your resolvers, and ensure your schema remains completely unchanged for your users. What you'll learn: Understand the core architectural differences between FaunaDB and DynamoDB data modeling; Map GraphQL schemas and queries directly to highly efficient DynamoDB single-table design patterns; Rewrite Apollo resolver functions to perform equivalent create, read, update, and delete actions in DynamoDB; Implement modern DynamoDB best practices, including efficient key structures and query optimization; Validate API contract compatibility to guarantee zero breaking changes for frontend clients. The course begins with foundational concepts of database migrations and API gateways, then guides you step-by-step through refactoring your resolvers, and concludes with testing strategies to verify complete client compatibility. This course is designed for beginner to intermediate developers who have a basic understanding of GraphQL and want to learn practical backend migration strategies. No prior experience with AWS or DynamoDB is required to get started. Master the art of seamless backend migrations and upgrade your API infrastructure today.
